LIGHTING FIXTURE.

Application filed December 30, 1925. Serial No. 78,267.

. for the illumination of a table directly unforms.

derneath the fixture, while the other lamps may be controlled to illuminate the room both by light diffused through a surrounding bowl and by light directed toward the ceiling. V

An object of the present invention is to provide such a lighting fixture in which a glass bowl is associated with the lamps in such a way that the bowl may be swung downwardly to provide access to the lamps without ailecting the reflector.

Another object of the invention is to provide a fixture which may be provided with a glass inclosing bowl of pleasing design and ornamentation, and to so mount the bowl that it is protected against injury.

A further object of the invention is to provide a lighting fixture of this type having the hinge and catch mechanism hidden by an ornamented part of the fixture.

Other and further objects of the invention will appear as the description proceeds.

The accompanying drawing shows for purposes of illustration, one of the many'possible forms in which the present invention may be embodied, it being understood that the drawings are merely llustrative of the invention, which may be embodied in varlous In these drawings:

i Fig. 1, is an enlarged view of the central part of the fixture, parts being an elevatlon and other parts in section;

Fig. 5, is an enlarged sectional view taken on the line 5 5 of Fig. 1;'

Figs. 6 and 7, are sectional views takenon the lines 6'6, and 7'7, respectively, of Fig. 5 and showing the hinge and catch mechanisms; and

r Fig. 8, is a-sectional view taken on the hue 8- 8, of Fig. 1.

The present lighting fixture may be supported in any suitable manner, but for convenience, it is here shown as being supported at the lower end of a hanger rod or pipe '10, which is threaded into a hickey 11. A body member 12, is provided with a vertical hole 13, so that it may be passed downwardly over the pipe 10. This body member supports a plurality of arms 14 in any suitable manner. For convenience, these arms may be threaded into the body member as indicated at 15. The outer ends 16 of these arms are attached to and support a frame 17 which extends around the fixture. This frame is here shown as being hexagonal in form. A movable frame 18 surrounds the fixed frame 17, and is suitably attached to it by means of a hinge 19 and a catch mechanism such as a screw 20, arranged on the opposite side of the frame. In order that the fixture may have a more ornamental appearance, the frame 18 is provided with a number of ornaments 21 which extend upwardly as indieated. These ornaments may be such as to completely conceal the hinge and to render the catch unnoticeable. The frame is also provided with a number of depending members 22, which may be attached to the corners of the frame 18 by screws 23. The lower ends of these members may be bent inwardly as indicated at 24 and teardrops 25 attached as indicated. These depending members serve not only as ornamental features of the fixture, but along with the frame or ring 18 provide a convenient support for a glass bowl 26, which may be inserted into the frame from above and held in place by clips 27, indicated in Figs. 6 and 7.

The arrangement so far described, pro vides a convenient support for carrying the glass bowl in such a manner that it can be swung from the full line position of Fig. 2, down to the dotted line position, thereby providing access to the parts of the fixture ordinarily carried inside of the glass bowl.

l/Vhen a fixture of the above type is to be provided with a single lamp to give downward illumination and plurality of lamps to give general illumination, one may use the arrangement illustrated in Figs. 1 and 4:. Here a lamp socket 27 is attached tothe lower end of a hickey 11 and this lamp socket is adapted to carry a lamp 28 which extends downwardly along the axis of the fixture. Inorder that the light from this lamp may be directed downwardly, as onto a table,

and not onto the glass bowl, there is provided a suitable reflector 29, supported at the lower end of a shell 30. As here shown this shell is in the form of an inverted cup shaped stamping, provided with a hole 31 so that the lower end of hickey 11 may pass through, and with a number of holes 32 to accommodate the lead wires. In order to reinforce the construction a number of washers 33 are lamps, 'to be described.

if-shaped brackets 35 are fastened to the upper end of the shell 30 and provide supports for a number of electric lampv sockets 36, which project obliquely downward and surround the central lamp socket 27. The lamps 37', carried in the sockets 36, are preferably located slightly below the frame 17.

These lamps. are adapted to illuminate the glass bowl 26, which will diffuse the ligl'it downwardly and reflect a part of it toward the ceiling. These lamps may be connected by wirescarried out through the hickey as,

7 indicated.

\Vhile the lower part of the glass bowl maybe closed,'if desired, it is preferable for ornamentation: purposes and in order to provide access to the central. lamp 28, that a central opening be provided in the glass bowl. This opening is indicated at 38. The

lower end of'the light unit may be conveniently finished ofi by a stamping 39 which covers the lower end of the glass bowl 26 and which-extends up through the opening '38; The stamping is held in place by a corrugated ring 4.0 which has projections ll resting.

on the upper surface of the glass bowl underneath the lower end of the reflector. The stamping 39 may carry anuinber ofornaments 452, if desired. The central lampQE may be controlled by means of a pull cord tiiwhieh operates the switch inthe socket 27. The outer lamps 37 may be controlled by a canopy switch, or otherwise as desired.

From the foregoing it will be apparent that one is able to obtain direct illumination from the central lamp when it is desired tov light'a table, or the like, directly underneath the fixture. When, however, one desires to obtain general illumination in the room, the upper lamps may be'switched on. These lamps may operate with or without the central lamp. They will be concealed by the glass bowl, and an even, pleasing, illumination will result. The light will be reflected fromthe inner surface of the glass bowl and from the outside of the reflector 29 in such a manner that the reflector will not be apparent when looking at the fixture. The central lamp may be removed readily, and access is provided to the outer lamps for replacement or cleaning, by merely unloosening the catch screw 20 and swinging the bowl downward to the position indicated in dotted lines in Fig. 2.

It is preferable that the opening 38 be comparatively small so that it willbe pos sible tohang the lighting unit higl'ier than is ordinarily possible in dining room fixtures. By making the opening small it is possible to raise the unit without bringing the lamp, filaments into the line of-vision ofthe diners thereby avoiding the objections to low hung fixtures in commonuse. By making this aperture small there also results a, better control of the light'c-onfining it chiefly to the table. This is of particular advantage when the daylight lamp is used; in the inner reflec tor for the downward light,'as the artificial daylight is confined to the table. A warmly tinted glass bowl emits. a light ofa. warmer color to the face of the diners andthejwalls,

ceilings and other parts of the room.

It is obvious that the invention may be embodied in many forms and constructions within the scope of the claims, and I wish it to be understood that the particular form shown is only one of the many forms. Various modifications and changes: being pos sible,-'I do not otherwise limit myself in any way with respect thereto. I
